https://en.wikipedia.org/wiki/Computational_fluid_dynamicsComputational Fluid Dynamics (CFD) is relatively young science, where the fluid dynamics is being simulated in a computer. In practice, CFD engineers usually distinguish three phases of each CFD project workflow:


  1. Preprocessing
    • Geometry creation or import
    • Geometry cleaning and preparation
    • Mesh generation


  2. Processing
    • Simulation
    • CPU time
    • Convergence
  3. Postprocessing Evaluation Results (integral quantities, visual, …)
    • Evaluation results
    • Integral results
    • Visual results


This Preprocessing training is a special course on preparation of CFD simulation cases for (not only) OpenFOAM CFD toolbox. In principle, the preprocessing phase is very similar across all of the CFD codes.
